[PATCH] virtio: add kernel-doc for map and vmap members

[John S <xaum.io@gmail.com>]

Document the map and vmap members of struct virtio_device that were
added without kernel-doc descriptions.

This fixes the following warnings when building with W=1:

  include/linux/virtio.h: struct member 'map' not described in 'virtio_device'
  include/linux/virtio.h: struct member 'vmap' not described in 'virtio_device'
